The future of perovskite solar cells has just got brighter—come rain or shine

Widely known as one of the cleanest and most renewable energy sources, solar energy is a fast growing alternative to fossil fuels. Among the various types of solar materials, organometal halide perovskite in particular has attracted researchers’ attention thanks to its superior optical and electronic properties. With a dramatic increase in the power conversion efficiency (PCE) from 3% in 2009 to as high as over 22% today, perovskite solar cells are considered as a promising next-generation energy device; only except that perovskite is weak to water and quickly loses its stability and performance in a damp, humid environment.
